1. /THE/ Gods of metal music, although they let themselves down with the albums where they experimented with their sound, namely The More Things Change, The Burning Red and Supercharger (which admittidly contain good songs). Found retribution with the almighty "Through the Ashes of Empires".

2. The pegs on your guitar's headstock that you use to tune your guitar.

3. Band that features the legendary Robb Flynn. Who is in turn the god of all metal.
1. Holy fucking hell have you heard Imperium by Machine Head? They are truely teh gods of metal!

1. One of several flattened pegs found at the top end of a stringed instrument, which when manually turned with the hand, adjusts the pitch of the corresponding string :: TUNING PEG

2. (Warner Bros, 1972) Title of an album by heavy metal pioneering band Deep Purple, featuring the band's all-time biggest hit "Smoke On The Water"

3. (1992 - ) Heavy metal band from San Francisco, very influential on harsher, more aggressive-sounding metal bands that would arise later in the decade. See for more information
One day, Robert Flynn of Machine Head was jamming along with Deep Purple's "Machine Head" album, but the low "E" string on his guitar was out of tune, so he had to turn the string's machine head.

Not only one of the greatest metal bands of all time, but also the name of Deep Purple's (one of the founding fathers of metal) greatest album. This name is synonymous with heavy music. And so it should be.

"I just cant get over how cool Machine Head sounds 20 years on."
